FKIE_CVE-2006-6982

Vulnerability from fkie_nvd - Published: 2007-02-08 18:28 - Updated: 2026-06-16 22:34
Severity
Summary
3proxy 0.5 to 0.5.2 does not offer NTLM authentication before basic authentication, which might cause browsers with incomplete RFC2616/RFC2617 support to use basic cleartext authentication even if NTLM is available, which makes it easier for attackers to steal credentials.
